FAQ: What Size Is A Water Heater Element Wrench?

What size wrench fits a hot water heater element?

and 1-7/8 in.

What size are hot water heater elements?

Electric water heater elements can be different in size, but the most common is 12″ (300 mm).

Are all water heater elements the same size?

Does the length of a water heater heating element make a difference? No, not as long as you have the proper voltage, watts and style. Shorter elements have a larger diameter therefore the same surface area.

Can you change a water heater element without draining the tank?

It is possible to change your water heater’s heating element without draining your tank. Although, keep in mind that it can be a bit more challenging.

What is the purpose of heating element?

What is a heating element? A heating element converts electrical energy into heat through the process of resistive (otherwise known as Joule heating). The electric current passing through the element encounters resistance, which produces heat.

Does it matter what wire goes where on water heater element?

No, it does not matter which wire goes to which heating element terminal in this case – electricity can flow in either direction. Remember to replace the plastic cover that protects the wires and terminals before pushing the insulation back in place and then replacing the water heater element cover.

Are hot water tank elements Universal?

There are three types: screw in, bolt in and clamp in. They all have different wattage ratings and can work on either 120 or 240 voltage. Check your state and local codes before starting any project.

Will a water heater work with one element?

Yes, a water heater can still run if the bottom element quits. In most water heaters, the top heating element controls the thermostat and will still work even if the bottom element fails. So provided the top heating element is working, it can still produce some hot water even if the bottom heating element fails.

Can I replace a 3500 watt water heater with a 4500 watt?

It is ok to install lower watt: replace 4500 with 3500 as long as voltage is same. Lower watt means less heat, so element can last longer.

How can you tell if a heating element is bad?

Touch a probe on the multitester to each screw on the element. If you get no reading, or a maximum reading, the element is bad. Elements do have some resistance, so a reading of 10-16 ohms is normal, with higher ohm readings for 3,500 watt elements and lower readings for 5,500 watt elements.

Should you replace both water heater elements at the same time?

It is also the element that cycles on first because of the temperature drop when water enters the tank. I recommend replacing both elements since you have to drain the tank to clean flush the sediment out anyway.

How much does it cost to replace a water heater element?

Heater Element Replacement Cost The typical professional charge to repair your heating elements is $200 to $300. There are two of these in each unit, one at the top and one at the bottom. The top element controls the bottom element and, if it goes bad, your unit won’t be able to generate hot water.

How tight should a water heater element be?

If it’s a screw-in type heating element, use a wrench to twist the element clockwise until it’s tight. Unless the new element tells you to, you don’t have to use Teflon tape on the threads. Make sure the element is secured snugly against the tank opening, or the tank will leak from the opening.

What causes a heating element to burn out in a water heater?

What Causes a Heating Element to Burn Out? Only electric water heaters rely on heating elements to warm up the water in the tank. Heavy gauge wires provide electricity to the components of your unit, so a poor connection between the wires and the water heater could result in the element giving out.
